Isaac is gone from New Orleans, but errant tree limbs, downed power lines and clogged catch basins are not. Mayor Mitch Landrieu is expected to address the state of the city this morning at 10:30 a.m., giving an update on the clean up effort and restoration of important infrastructure.

The lack of electrical power appears to be the greatest source of vexation for residents as temperatures today are expected to rise toward 100 degrees.

By Thursday evening, the National Guard had set up ad hoc distribution centers in Algiers, eastern New Orleans and the Bywater to hand out ice, water and food. The American Red Cross has shelters spread across the region.

Garbage collection begins today. The Landrieu administration has directed residents to separate household garbage from Isaac debris before hauling it to curbs.
